Abstract: A structural mounting system for mounting of structural components (14, 15) includes a base section (10) and a co-operating section (11) each of which in use is secured to a respective structural component and which are assembled together. The base section (10) in cross section includes an undercut (21) and the co-operating section (11) in cross section includes a leg (35), having a toe (34) projecting laterally to engage the undercut (21). When the sections (10, 11) are being coupled together the co-operating section is rotated about its longitudinal direction relative to its final position so that lateral movement of the toe (34) to engage beneath the undercut (21) requires the co-operating section to rotate about the longitudinal axis relative to the base section to adopt its final position. Spaced linear restraint points (60, 61) and a rotation restraint point (62) together defining a triangle of points of contact to make the assembly of sections rigid. The sections (10, 11) have co-operating formations (36, 38, 46, 47, 48, 71, 73, 76) which require rotation of the co-operating section (11) relative to the base section (10) in a direction opposite to the direction of rotation to effect engagement of the toe (34) with the undercut (21) during close coupling of the two sections together until the toe (34) reaches the undercut (21) and the co-operating section (11) can rotate to its final position.

Title: Automated method and apparatus for hydrating soft contact lenses
Inventor: KEENE DARREN SCOTT
IPC: C08J7/02
Filed: 1996-04-29
Granted: 2007-07-24
Abstract: An automated means for hydrating a molded hydrophilic contact lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. A first rotary transfer device then hands the first hydration carrier to a second robotic assembly which immerses the first hydration carrier in a hydration bath to hydrate the lens and to release the lens from the lens mold. While the lens is immersed in the hydration bath, each lens is transferred from its respective mold to a lens transfer means found within the top chamber plate. After a predetermined period of time, the second robotic assembly removes the first hydration carrier from the hydration bath and hands the hydration carrier off to a second rotary transfer device which rotates the first hydration carrier and aligns it for transfer to a third robotic assembly. The third robotic assembly then carries the top chamber plate and contact lenses through a series of steps in which the lens mold carrier and lens molds are removed from the top chamber plate. The lenses carried on the lens transfer means are then flushed and transported for assembly with a hydration base member to form a second hydration carrier for processing the lens in subsequent extraction stations. The second hydration carrier is then transported through a plurality of flushing or -64- extraction stations wherein fresh deionized water is introduced into the hydration chambers at each hydration station to flush leachable substances from the hydration chamber. At each flushing station, fresh deionized water is introduced into the hydration chamber to remove previously extracted impurities and the products of hydrolysis. A final robotic dis-assembly device separates the top chamber plate and lens transfer means from the hydration base member, to provide fully hydrated lenses in a concave lens holding means ready for transfer to inspection and packaging stations.

Granted: 1999-12-28
Abstract: A method for supporting end to end VC oriented service between mobile hosts. Included are protocols designed for a micro-cellular wireless environment in which mobile hosts make frequent transitions between cells. A VC rerouting procedure minimizes the effect of frequent hand-offs by extending routes and triggering a route rebuild only when performance as seen by an application degrades below a certain level. VC establishment and rerouting protocols assume the existence of separate signaling protocols for the wired and the wireless network, respectively. This minimizes the changes required to the signaling infrastructure used in the wired network while allowing the signaling in the wireless network to be customized for the unique requirements of that particular environment.
